A Caspase 1 é uma enzima que executa proteólise em proteínas, tais como em formas precursoras das citocinas inflamatórias, interleucina 1-β e interleucina 18, transformando-as em péptidos maduros. Pertence à família das proteases de cisteína, conhecidas como caspases, que quebram sempre as proteínas a seguir a um resíduos de aspartato. A caspase 1 é produzida como um zimogénio que é clivado em 2 subunidades (uma com 20 kDa (p20) e outra com 10 kDa (p10)) e depois transformada numa enzima activa. A caspase activa possui dois heterodímeros de p20 e p10.

Interage com uma proteína que contém um domínio CARD, denominada PYCARD (ou ASC) e está envolvida na activação de processos inflamatórios.

A Caspase 1 mostrou interação com NLRC4.
